AIC-7901 controller for Ultra320 SCSI Host RAID 0, 1, 10 support I have 4 disks which are configured in 2 Raid1, the problem is when I try to install FreeBSd from the installer cd, it shows only the separated disks. I've added also ahd_load="YES" into /boot/loader.conf on the installation cd, also on the boot prompt load ahd load ahd.ko and then boot but again with no success . It were recognized only the 4 disks as separated. How can I make it recognize the raid ? Thanks in advance. From gibbs at FreeBSD.org Tue Oct 6 13:05:23 2009 From: gibbs at FreeBSD.org (Justin T.

The Adaptec U320 controllers have no built-in support for RAID. SW RAID support is provided by the BIOS and the windows drivers. Unfortunately FreeBSD does not support the Adaptec SW RAID meta-data, hence the disks are reported individually instead of as a single volume. -- Justin From enidv11 at gmail.com Tue Oct 6 13:08:23 2009 From: enidv11 at gmail.com (enid vx) Date: Tue Oct 6 13:08:29 2009 Subject: Not recognizing raid controller Adaptec AIC7901 In-Reply-To: <4ACB39EF.1010003@FreeBSD.org> References: <77b5ce830910060238qf61d697i3f846b8ce5954ae3@mail.gmail.com> <4ACB39EF.1010003@FreeBSD.org> Message-ID: <77b5ce830910060608t51773088t7354c1ee5ac1d4e5@mail.gmail.com> Thank you for answering, So if I have no possibility to install FreeBSD on aic-7901, but I want to use RAID can I user mirroring with gmirror. Is this a good idea, can you give me an advice how to add redundancy to my data. Also is there a plan in the future to support this kind of controller? Enid On Tue, Oct 6, 2009 at 2:37 PM, Justin T.
